Great work, thanks!

The driver works fine when I'm only my notebook display with no external
monitor connected.  When I'm using the same config file as above (one
screen) but with an external monitor connected, X and the WM load, but
when I start to move my mouse, it crashes.  Works with the radeon driver.

Config and X log:

I also have problems with dual-head configurations.  If I configure
dual or clone setups using 'Option DesktopSetup', X starts to load, but
crashed shortly after and both the notebook display and the external
monitor stay black.

The log just says the following and is the same as the one above

Fatal server error:
Caught signal 11.  Server aborting

Is this a known problem?
